I've had it for a while. Very fine tool - top of the line quality. Their website has several videos showing how the tool works. It is primarily designed as an EDC for fire and rescue folks. It's designed to be removed from the case and opened with heavy gloves.
It's not a multi-tool - its in a pocket knife format. The blades swing out of the casing like a pocket knife.
It has a:
Serrated knive - very large open assist cutout to open with heavy gloves. Seatbelt cutter - reverse serrated with a blunt end and curved to catch belt and cut.
Window glass saw - saw-like blade with sharp end. Designed to puncture and cut laminated glass (windshield). Used with 2 hands.
Window break - heavy, blunt point at end for cracking safety glass. Always exposed at end of handle.
Pry blade - heavy duty flat screwdriver used for prying, etc. Also has bottle opener.
The glass saw and the window break are replaceable if they wear out. The manual shows how to do it - it's easy and is done by pushing on the blades at 90 degrees which slips them out of the handle. They are very firm and could never come out accidentally..
plus other standard Victorinox items like toothpick, tweezers, awl, phillips screwdriver.
It comes in a high-quality, cloth case (red) with high quality velcro which closes firmly and is easy to open. Also has a very wide belt loop for those large duty belts. The knife also has a long cord loop making it easy to pull out of the holster with gloves and by touch.
Another cool feature is the GITD handles. With a short charge, they glow very brightly yellow for a long time.
A very nice tool which would serve folks that need rescue tools at the ready. I keep mine close by in the car.
Be aware there are two models - 8623N has a standard blade and 8623MN has the easy open blade with the large assist cutout. This is the one I have - I guess the plain blade would be for folks that wouldn't be using gloves (whoever that would be?)
